Action star Jeremy Renner (The Hurt Locker, The Avengers) delves into the shadowy world of investigative journalism as Gary Webb, the real-life journalist who remains one of the most controversial of our times. In the vein of “All the President’s Men,” this thriller follows Webb’s allegations that the CIA supported Nicaraguan contra efforts through the importation of crack cocaine into American cities. Threatened against releasing his evidence, in 1996 Webb nevertheless wrote a three-part series in the San Jose Mercury News — paying for it with his reputation and ultimately his life.
